' To all whom iii-may concern:

Beit known that I, WALTER S.':ADAM:S,' a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in. Looking Devices for Car-Seats, of which the following is a specification. I I

The object of, my invention is to construct a car seat having a reversible back so that the cushion section cannot be removed from the frame unless the back is in the mid-p0 Fig. l; and Figs. 5 and 6, are views of modi- I fications of my invention.

A is the frame of the car seat having a surface or upon which rests the carrying frame B. This frame is curved'on its lower side so as to slide from the center position,

Fig. 1, to either of its extreme positions, one of which is shown in Fig. 2. In the present instance projecting from the frame Bare pins 6, b, which enter the frame of the seat cushion D. The supporting frame B has a vertical slot 7) formed by flanges projecting from one side of the frame. v E is the back of the seat, having arms C pivoted to the shaft F which extends .from one end of the seat to the other in the present instance. On an extension 0. of the arm C is a pin 0 which projects into, the slot in the frame B, so 'thatas the back is shifted from one side of the seat to the other the seat cushion section I) will be moved in the opposite direction to make the seat comfortable for the occupant. This is a common construction of car seats of-this type.

or bolts 2'. These plates are bent so as-to ex-. tend below the line of the shaft F and are of such length as to allow the seat cushion to' move to either of its extreme positions without interfering with the shaft F. The two plates I, I are also spaced apart at the center a sufficient distance to allow for the pasran smrns rx rrivrorricni sage of the shaft between the plates when j the back section is in the position shown in Fig. 1. When it is necessary to remove the seatsection, the back section is shifted to the central position, Fig. 1, and as the space between the plates is in line with the shaft F, the seat section can be raised off of its supports and removed, .but when the i back is moved" to one side or the other of theseat structure, the plates I, I prevent the removal of the seat from its supports, as the plates underlap the shaft F. These plates also prevent the tilting of the seat section.

While I have shown the platesI, I secured to each end of the cushion section, as illustrated in Fig. 3, a single pair of plates may be mounted atv or about the center .of

the seat section to accomplish the same pur- I ose. In Fig. 4, I have illustrated a modification in which the slot 71 is formed in a plate I the arms 2' of the plate extending toward each other and'being spaced a suflicientdistance apart to allow for the passage of they shaft.

In Fig. 5, I have illustrated a modificaseat sections are in the central position the.

pin d on the seat alines with the space hement is more quickly effected; a

The. main object of the invention is to provide means for preventing the accidentalremoval or tilting of the seat cushion section when the'seat is in position to be occupied by passengers, The plates may-be shaped so as to form stops to limit the outward tween the arms, and when the parts are i moved from the central position the engage.

movement of the cushion sectionwhen in y either. of its extreme positions.

The invention can be applied to any form of car seat and any of the ordinary means for simultaneously shifting the-cushion section andthe back may be employed.

I claim i 1." The combination in a car, seat structnre, of a frame; a seat support arranged to position it can be bodily removed from its slide onlthe frame; afseat section movably' mounted on-the seat support; a transverse shaft located under the seat section and having its bearings in the frame; an arm on said shaft engaging the seat support and another arm on the shaft to which theback is attached; with a guard having a slot located that when the seat is in the mid 2. The combination in a car seat struc-- ture, of'a seatsection and a transv'ers'e shaft {fix ted iii der the seat section; a slotted gi ai'd on one of said parts and an element 911 the other p rt with which the' uard'em; gages; a frame; aseatsupportarranged to slide on the frame and arranged to carry the seat section; anyarm' ontheishaftto which the'backof the seatis secured; and

means for causing the seat support to slide." as the back is shifted from one side to the other," the parts being so arranged that When the back is in the central position the slotof the guard on onepart Will be in line with the element on the'other part so that it the seat section can be bodily removed from the seat structure.
